CALCULATING-MACHINE.

My invention relates to improvements inl f1() calculating machines, and more particularly in calculating' machines of the class shown and described in the patents of the United States Nr. 1,040,059previusly granted to me October l, 1911, and Nr. 952,257, granted January 17, 1910 to Jahnz, in

which setting disks are .provided with radiallyshiftable teeth which are adapted to be set iii operative positions by means of cani disks. Machines of this type are proivided, with a single registering mechanism, and where it was desired to perform continuous additions of products, each product was at first transmitted by means of the setting disks to the numeral wheels of the registering mechanism, Whereu on the setting disks were reset to zero. hen the numeral wheels were reset so as. to transmit the product tothe-setting disks, and the carriage carrying the registering mechalnisingwas' shifted, so lthat the setting disks Werein position :for coperation with a different set of numeral Wheels,'and the value on the setting disks which represented the product was transmitted to. the said new setof numeral Wheels.. By repeating this .method all the products were finally summed up in their setiof numeral wheels. This method is simplified by setting the factors of the product from the beginning on the two sets of setting disks, so that by a single revolution of the machine crank the product is produced on two sets ofvnumeral wheels. lett in one of the sets of numeral Wheels, while itis erased from the other set, so that this set is again free to receive and display the new product, while at the same time the'new product is added to the product which has been left from the foregoing-operation or operatioiison its set of numeral wheels. Thereby the products can be sepa'- rately produced, and furthermore the sum.

of all the products is obtained by the same operation. Preferably the two voperations vare carried ont in such a way,

-The product is.

values are set on the-one hand on the setting disks located at the right of the machine. and on the other hand on the set-- ting disks located at the left of the machine, and preferably between the sets of setting disks a few setting disks are left which arc not used at all, because thereby mistakes are more vsafely avoided.v

yOne of the objects ot' the 'invention consists in s0 constructing the calculating ma-4 chine, tliat. thee-said simultaneous setting operations are performed in a Aconvenient and reliable way, so that they can be performed with great speed andinistakes are avoided. i

lilith thisl object in view my invention consists in providingmeans whereby corresponding setting disks of both 'sets can be operatively connected, so that by setting a value in one set of setting disks the same value appears in the other set.

In order that my invention bel more. clcai'liY understood several examples embodying the same have been shown in the accompanying drawings, in which the. same 'letters of reference have been used in 'all the views to indicate corresponding parts.

Fig. 9, is a detail view of a part shown in Figs. 7 and 8, Fig-10, is a front View of a further modification, the cover of the casing, the registering mechanism, and most of the setting disks being removed, and Fig. 11 is a vertical cross-section similar to 'that shown in Figs. 1, 5 and` 7 and shovv-l ing a further modification.

- Before describing those parts of the nia-V i l larly relates, I shall at first describe alcalculating machine of known construction which my invention is preferably embodied.

`But i Wish it to be understood, that this.v

known type is described merely, because in my opinion 'itis necessary for a clear un-l derstanding of thel invention, and that the' invention is not limited to the use in the type of a 'calculating machine shown in l adapted tov be rotated by means v of a crank 15- lthrough the. intermediaryof gear'wvheels 2 and. 3. To the said shaft setting disks '5 are rigidly secured which carry radially` shiftable teeth 6 adapted to be shifted' into or out of operatively positions by means lof rotar cam disks 7. In front of the settino D disks a carriage or slide 8 is located which is adapted to be -shifted in a ydirection par` allel to the shaft 1, and -Whichf provides a' support for a shaft 10. On the-latter a plura ity of numeral wheels 9 are loosely mounted for independent'.rotation.

gear Wheel 11 which is in engagement With a gear wheel 12. All the gear wheels' 12 are' loosely mounted on a .shaft 13, and they are located in theplane's. of the teeth 6 of the setting disks 5 and in such positions as --to v same in vits positions, and the vnumbers made on the outer circumferences of the numeral p' Wheels can vbe read through peep holes 19 ybe adapted to be rotatedthereby. Each of the numeral Wheels 9 is acted upony by a locking' paivl 14 which is adapted qto lock Athe made in the cover 20 'of .thecasing Between successive numeral Wheels carrying mechanism is provided which in the example shown in Figs. 1 and 2 consistsxof a lever 15 constructed in the form of'a hammer and having a rocking support'on a shaft 16 disposed parallel to the shaft 10.v Each of the numeral Wheels is lprovided With a pin 17 which is adapted to engage the lever 15 and to rock the same, Whenever the 'numeral Wheel passes from the nine position to the zero position,"o'r vice versa. "Thereby the beveled, face-'15of the lever 15 is brought into the 'path lof a tooth 18 which is located on the coperating setting disk 5 'and is adapted'to be rocked by the lever 15 laterally and into position for/engagement With the intermediate gear Wheel 12 con# nected With thel numeral wheel of the next f higherorder. Thereby the said intermediate gear Wheel and the numeralwheel oonneted therewith are advanced a distance' corresponding to one value. After the tooth 18 has thus carried over the ten to the adjacent numeral Wheel, the rocking lever 15 isreturned into inoperative position by means of a cam 21 secured to the setting disk p Each of the numeral Wheels is rigidly connected With a 5. Ordinarily 'in machines lofi-this type' a. further registering mechanism is provided on the.' carriage 8 and coaxially of the aforesaid main registering mechanism, and this subsidiary registering mechanism has the function to count the number of revolutions to the'machine crank 4. In the machine shown 1in `Fig.'1 this revolution counting mechanism'is associated .Withthe disks 9 as1 usual in accordancezwith' my construction and arrangement of parts. from theI shaft 41 vofthe setting mechanism by means of, a single tooth 22 (Fig. 2) which advances a numeral Wheel -of the revolution counting mechanismwhich corresponds either to the units, Ithe tens, the hundreds, ete., according tothe' position vof the carriage 8, as has been describedmor'e in de- .tail With reference ,to F ig. 1 of my aforesaid.

and if necessaryl the revolutions counting mechanism, arev provided '."With resetting mechanism. As'shown, the resetting mechanism is provided by the shaftIO which, as is shown in detail l1n' Fig. 3, is equipped at tri-ting'the-same, and with radial pins. 2l onefor each of the numeral Wheels and in nut 23, 'bywmeansf of a* cam 'face 26 and" against the action-of a .spring 27. To prevent the numeral Wheels from taking 4part are interposed between the. same. .A Referring now to those parts of the calculating machine to which my. invention more particularly relates, reference will at first be had `to Figs. 1 and 2, Wliich'show one em' bodiment of the invention. As appears from the said figures, -al frame 29 has arocking support on a'shaft 31 mounted on brackets- 30. On the said frame shafts 33 are mounted for rotation, and the number of .thesaid shafts is equal to the number of setting disks provided. in each of the sectional settingmechanisms. On each of the shafts two gear Wheels 34 andf are rigidly mounted,ion"e of which, 34, is in position for enga gement Awith spur 'gears 7 y connected with one of the setting disks of one'set, While the other one, 35, is in position for engagementwith spur gears 7 connected with the corresponding setting disk 7 of the other set. The frame 29 can be rocked by means of a handle 32 with the gear Wheels 34 and of all the shafts 33 in or out of engagement With the spur gears 7 and 7 respectively. If now the frame 29 is rocked with its gear Wheels 3a and 35 in operative positions, and a value is set in the right hand set of setaccording to the position ofthecarriage 8v Patent Nr. 1,040,059... The numeral wheels,

The said pins are adapted to engage noses 25- provided on the numeral Wheels, for Which purpose the shaft 10 is shifted, dur- 4 ing the first part of its rotation by t-he thumb l A It is operatedl iii-this shifting movement, ,short sleeves 2S land its coii'iplementary `salue, a're ing corresponding setting disks of'both sets.

in this example the gear Wheelsare located out of the plane of the spur gears 7 and 7 and they are adapted to be brought into cooperation with the said spur gears by being shifted in a directionparallel to the shaftv l.

In the example shown in Fig. as the frame :29' which carries the gear wheels and is shiftable by means of upper and lower guide members 37 and 8S.

.'ln many calculations, for example in rebate calculations, it is desirable to set in one group of setting disks a certain number, and simultaneously in Ithe other group aA number which coinplenientsithe first number to the next higherpower of ten. For exan'iple, if in one of the groups the numi'ier T68 is set, the other group should receive the number 232, so that the sum of both numbers is 1000. One of the objects ofthe invention 'is to so construct the calculating machine, that, the said values, 'that is the setby means Vof a singleoperation. Vfith this ol ject in View the gear wheels, which, asin the examples described with reference to Figs. 1 to l, connect corresponding sett-ing disks of both groups with eaclji other, are connected with each other in such a way, that the said gear wheels rotate in opposite directions. This may be done for example by providing additional 'gear wheels intermediate the said corresponding gears` Wheels,

by' means of which the rotation of the set-v ting disks of one group is reversed as to the corresponding setting-disks of the other group. In this case'the setting disks on whichthe main lbasic number is set are atfirst set in their zero positions and there upon shifted in the ascending` order of their numbers, until the desired number reached,

so that the setting disks which are designed i to receive the 'complementary numbers and i6 and 4l secured thereto.

are at first turned inf4 the descending order Vof the numbers.

main or basic value' .t in their nine positions are'.

y Before furtl'ier describing my neu7 method i I deem it best to first describe'mechanism whereby the method may be carried out.

As appears from-Figs. and 6, a frame i0 has a rocking support'on a shaft 39, and it is adapted to be rocked by means .of a handle il. i-it one side the said frame carries shafts 4'2 each of which has-gear wheels Atthe opposite Athe basic number.

frame, and each o f. the said shafts gear Wheels lo and 47 secured thereto. The gear ujheels and of corresponding shafts 42 and 43 are in engagement with each other7 and corresponding gear wheels 46 and 4T are connected with corresponding setting disks of both sets. The' frame t() can he locked -in` operative position by any preferred means. If the machine ispdesigned to be used only for calcuiations of one character, it may be rigidly secured to the machine frame. For performing the aforesaid double calculations, the setting disks of one ,.sct, which are designed to hare the compie mentary numbers set thereon, are at first set- .in their nine positions, with the' exception of the setting disk which receives thedigit of the lowest place of the number to be set.

This setting disk is set on the next value be-v yond the nine position, that is the ten position. Should at the last place orplacesof i the number be the zere, the corresponding setting disks are set in their Zero positions. All the setting disks corresponding to the main or basic numbers are set in their zero positions. Non' the rocking frame i() is rocked into operative position, whereupon the machine is ready for use. The basic number is nou' set on its setting disks which have before been set on their zero positions, respectively. Thereby the setting disks of theother set are simultaneousl).lv set from their nine and ten positionsto the numl'iers which are the con'iplementary nui'nbers ot If nou' the machine 100 crank is operated in the usual way, the values setje-n the sets of setting disks are transmitted to the numeral Wheels. To understand the method, it may be assumed that the number 7,680 and its complementary 105 number 2320 is to beset on the setting mechanism. The setting disk which cm'responds to the zero is placed in iJ position, and

zero it is not turned at all, so that also the cor. responding disk remains in its Zero position. In the complementary group the setting disk 1which corresponds to the digit has been placed in its Sten position, and it is turned' backward into its 2 positiom'lthat is' Aa distance which correspondsl tol eight units. These'eight u nits are transmitted to the corresponding settingV disk of the other group, which is thereby set from its zero position to its eightposition.l The number 6 is now set on the third set-ting disk by turning the no third complementary disk from its nine position into'its three'position,'that is at an g angle which correspondsto six values. These l i i l i i six vaines are again transmitted to the other group of setting disks, so that the third set; ting diskis turned six values out o f its zeroI position and shows the number-six. n'av similar Way thenumbers seven andtwo are placed on the setting disks. Therefore I side rotary shafts a3 are mmmted on the hare in one set of setting disks the i-iuniber i3@ A the sum 'of which numbers-is 10000.

lscribed with reference to Figs.

For this purpose reversing.,

lIn Figs. t and S I have shown an example in which at will calculations of. the character described with' reference to Figs. l tol. or calculations ot'vtheehara'cter de'- 5 and 6 maybe performed. means are included in the mechanism connectingy corresponding settingdisks. The mechanism connecting correspondingsettingl disks is similar to the mechanism described -with reference'to Figs? 5 and 6.' Rigidly mounted on -a shaft 53 is a gear'wheel 52 which is in engagement with one of the setting disks l'i'. At its opposite end the said shaft carries a'sleeve 55 onl which gear wheels 48 and 51 are mounted, and which is'longitudinally slidable on'thejshaft Abut takes part in its rotation. On a shaft 54 a sleeve 56 .is longitudinally slidable which has gear wheel-s 49 and 50 rigidly mounted' thereon. The slceves'55 and 56 are con- 'nected with each other by `a member 57 engaging in circumferential grooves ot the said sleeves. Tn the'pcsition shown in Fig. 8 the movement of one ot' the setting disks is transmitted to the other one through the intermediary of the gearwheels 48, 49, and 50. so that the movement .is reversed, and the calculation described with reference to Figs. '5 and 6 is performed. AThen the sleeves 55 and 56 are shifted tov the left, the gear wheel and the setting disk. get out of engagement with one another, andthe gear wheel .51 .gets in direct engagement.' with the gear wheel connected with the lsetting disk.` so that the movement from one to the other one is transmitted fsense.

chine. To thefslide a handle 64: is secured which projects through the rear wall 65.

.In Fig. 10 .I have shown mechanism whereby the ygear wheels and the cooperating cam and setting disks are automatically thrown outl of operation whenthe machine crank is .being operated. Therebythe operation di 'me machine is made moresim'ple. i

F or the matter of clearness only two cooperating setting disks 7, lTand one pair of coupling gear wheels 66 and 67 mounted on a common shaft 68 have been shown. The said shaft is'mounted on a frame 69,'and it is under'the action ot' a 'spring 70 which tends to shift the same in the direction from right to left. fr lever 71 and axlongltudinally shiftahle rod 7 2 normally hold. the l number 2820,
